I started with the static ports half way between the flap and stabilizer on both
sides of the fuse. I compared airspeed with the GPS and I am slow by 12 mph.
I disconnected the static line from the back of the Dynon and I am fast by 12
mph. I was thinking of trying the fuse sides in front of the instrument panel.
Someone must have a good location.

Hi Chuck,
I don't know which model 601 you have and it probably matters a lot.
On the XL the static port on the drawings is about half way out on the
bottom of the wing. It is on a tube that runs parallel to the pitot
tube. This works well. I haven't done a formal calibration but the GPS
speed and Dynon airspeed always seem quite close.
The fuselage on the XL doesn't have any points where its side runs
parallel to the line of flight. This means there is no "Neutral"
position for static ports. It also means there is no yaw stability
until the rear end gets more than 11 degrees from straight ahead (the
rear fuselage forms a 22 degree angle at the aft end).
Good luck,
Paul
XL about done with phase I flight test.

You won't have the same airspeed as a GPS. They measure differently. The pitot
system is really an air pressure system.
I placed my two teed static ports behind and below the canopy hinge. They connected
to both a dynon with AOA pitot and an old style anaolg AI. They both read
the same, even in a slip they provide a reliable indication.
